SHAKER.

Specification of Letters Patent.

Patented Nov. 8, 1910.

Application filed March 12, 1999. Serial No. 482,937.

To all whom it 'may concern:

Be it known that I, ERNEST K. I-IooD, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Shakers, of whichthe following is a specification.

In the manufacture of condensed milk, it is necessary, after theprocessing has been completed, to subject the milk to a violentagitation in order to reduce it to the smooth creamy condition whichcommercial conditions require; as, in such processing operations, theproduct becomes lumpy and uneven. Other food products are also benefitedby such agitation or shaking.

The object of my present invention is to produce a machine by which thiswork may be quickly and efficiently performed.

Referring to the accompanying drawings, which are made a part hereof,and on which similar reference characters indicate similar parts, Figure1 is a top or plan view of a machine of the character in questionenrbodying my present invention; Fig. 2 a view artly in side elevationand partly in longitudinal vertical section as seen when looking in thedirection of the arrows in the broken line 2 2 in Fig. 1; Fig. 3 atransverse vertical sectional view as seen when looking in the directionindicated by the arrows from the broken line 3 3 in Fig. 1; Fig. 4 anend ele vation; Fig. 5 a detail sectional view as seen when looking inthe direction indicated by the arrows from the broken line 5 5 in Fig.1; Fig. 6 a view similar to a portion of Fig. 2, but on an enlargedscale, and showing the follower plate in full lines, and Fig. 7 a detailsectional view also similar to a portion of Fig. 2, but on an enlargedscale.

In this machine, upon a heavy base 21 I mount two side members 22 and23, and these constitute the frame of the machine. Centrally, in thisframe, I provide large bearings, and in these bearings I mount a crankshaft 24 having two opposed cranks 24 and 24". Upon one end of thisshaft I place a driving pulley 25, and upon the other end a fly wheel26. Also, in the said frame sides 22 and 23, I securerods 27 and 28which form slides upon which the cages containing the material to betreated are mounted. As best shown in Figs. 1 and 2, these rods -27 and28 are each carried by three upwardly extending arms on the sides 22 and23. There are two of these rods or slides at each end of themachine-there being two cages of corresponding form and character.

Each of the cages in question consists of two end plates or heads 31 and32, and a suitable number of side and bottom rods 33. In theconstruction shown there are eight of thes-e rods 33 in each cage-threeat each si e, ment vof which is best shown in Fig. 4. These rods aresecured to the heads 31 and 32 by means of nuts on each side. It isdesirable that the inner face of the heads 31 should be non-obstructed;and, therefore, as best shown in Figs. 2 and 7, I provide countersunkopenings to receive the inner nuts 34, while the outer nuts 35 and 36arevcarried by the outer ends of the rods on the outside. This makes avery strong and comparatively inexpensive cage, capable of receiving andcarrying the cases of produce to be treated.

The heads 31 and 32 are provided with extensions 27 and 28, which,respectively, extend over and form bearings upon the rods or slides 27and 28. Said rods being fixed in the frame, these extensions formbearings which move on said rods, as the cages are thrust back andforth. In the outer heads 32 of these cages I place clamping screws 55having hand wheels 56 and jam nuts' 57. These clamping screws 35 operatefollower boards or plates 38, between which and the heads 31 the casesof material to be treated are placed.

Extending between the crank shaft 24 and the heads 31 are connectingrods 41.

At one end each connecting rod has a bearing which surrounds thecorresponding wrist on shaft 24, and, at the other end, is provided withanother bearing which surrounds a wrist-pin 42 mounted in ears 31 onhead 31. These bearings engaging wristpins 42 are split at one side, andare provided with take-up bolts 43 having jamnuts 44 thereon. In a heavymachine of this character, having a rapid motion, it is highly necessarythat these bearings have a very accurate adjustment. The splits in thesebearings and the take-up bolts referred to, afford a means foraccurately effecting this adjustment. The bearings surrounding thecranks of crank-shaft 24 are also split, and the cap portions 45 aresecured to the and two atthe bottom,-the arrange I main portions bybolts 4G bearing ain-nuts 47 .Y Interposed between the parts 41 and 45are liners or shims 49, which, when the bearings become worn can betaken out and dressed down, after which, by means of the bolts 46, thebearings can be restored to their original degree of tightness. Sleevesor bushings of a suitable bearing metal preferably surround and are inimmediate Contact with the wrist and crank pins, as shown in Fig.v 5.

Having thus fully described my said in-Y vention, what I claim as new,and desire to secure by Letters Patent, is,

42. The combination, in a shaker, of a' frame, a double crank shaftmounted centrally in said frame, slides at each sideA of said crankshaft carried by said frame, cages mounted on said slides, connectingrods connecting the heads of said cages with the cranks of said crankshaft, each connecting rodbeing provided with split bearings whichengage the wrist pin, and suitable take-up bolts for adjusting saidbearings.

3. The combination, in a shaker, of a frame, a crank shaft arrangedcentrally therein having two central opposed cranks, slides carried bysaid frame at each side of said crank shaft, a cage mounted on saidslides at each side of said crank shaft, each cage being composed of twoheads and rods connecting said heads, the means of connecting the headsand rods being a series of nuts, and one of each of said heads havingcountersunk openings surrounding the rods to receive the nuts on theinner side of the head, whereby projections on the surface of the headare avoided.

4. The combination, frame, a shaft mounted centrally in said frame andprovided with two cranks opposed t0 each other, slides carried by saidframe at each side of said crank shaft, cages each composed of two headsa series -of bottom rods and two series of side rods mounted and adaptedtoV reciprocally move said slides, pitmen connecting the cranks with theheads of the cages, and clamping devices secured in the opposite headsof the cages for clamping the cases of material to be treated therein.

In witness whereof, I, have hereunto set my hand and seal atIndianapolis, Indiana,

this eighth day of March, A. D. one thousand nine hundred and nine.
